(This article was thought up after the author finished playing the Sirius line of the orange light game "Predators", but the main plot is about the heroine carrying memories to the next generation. The author is just a junior high school kid who can't write any amazing writing, so he just reads it as boring and tries not to be OOC. Clearance: There is a big age difference, but it's okay for wizards to have a long lifespan)
